Exporting maya calibrated camera as staring intrinsics and extrinsics

[josh]

Hey, i have a small number of calibrated cameras (5) in maya that i wish to import into zephyr as an initial estimate. I have both the extrinsic and intrinsic values for each camera and the distortion parameters. Im having success with exporting the internals into the browns model and can load them into zephyr, but need a bit of help with the extrinsic.

Will i be able to query the extrinsics straight from maya? Getting the rotation matrix and translation from the xform -m command?

Would i be able to query the Euler angles from maya and use them directly?

Is there a way in zephyr to load in a calibration without running reconstruction or alignment?

Cheers,
Josh

Hi Josh,

yes, you can use the XMP workflow for that. Here is the tutorial https://www.3dflow.net/technology/do...flow-tutorial/

could you please elaborate on how to import extrinsic calibration ?

The easiest way is the XMP wofklow, see as specified above https://www.3dflow.net/technology/do...flow-tutorial/ or this videotutorial https://www.youtube.com/watch?v=d0Q4ZBorKRU

You can eventually use the load photos with known parameters option.
